How to Measure Pressure
The Calibrator can be used as a pressure calibrator when you use it with the following
accessories:
To measure pressure:
•
Fluke 700-Series Pressure Module
•
Model 700PCK Pressure Calibration Kit (necessary because it provides the interface
module)
To source pressure:
•
A stable, hand-operated or automated pressure source
•
Fluke 700-Series Pressure Module
•
Model 700PCK Pressure Calibration Kit (necessary because it provides the interface
module)
See Figure 4-15 for how to connect a 700 Series Pressure Module to the Calibrator.
To connect a pressure module to the Calibrator and display a pressure measurement,
proceed as follows:
1.
Connect the 700 Series Pressure Module to the 700PCK input jack, and connect the
700PCK power supply to line power.
2. Using the adapter supplied by the 700PCK, connect the serial data cable from the
700PCK to the SERIAL 2 TO UUT connector on the rear panel.
3. Press the
m
key on the Calibrator. This activates pressure mode.
4. The Output Display shows the pressure value measured by the 700 Series Pressure
Module. The Control Display contains three softkeys: DAMPEN (on, off), SET
OFFSET (zeros the pressure module), and UNITS (pressure units).
5. If you are using any 700 Series Pressure Module except an absolute-pressure type
(Model Number starts with “700PA”), vent the pressure module to atmosphere and
press OFFSET to zero the pressure module.
6. If you are using an absolute-pressure type module (Model Number starts with
“700PA”) zero the pressure module as follows:
7. Vent the module to atmosphere.
8. Press SET OFFSET.
9. Enter the ambient atmospheric pressure in the units currently displayed.
